One of my fondest childhood memories is using paper cup telephones and even using them to amplify the songs playing on the radio. Based on similar lines is the RingIng Bluetooth Speakers. Crafted from flexible materials, lightweight and small in size, the design consists of two parts: Loudspeaker + Rubber Lens Hood. Simple and sweet!
RingIng Speaker is a 2013 iF concept design entry.
